-IMPROVEMENT IN BEDS FOR LEATHER-ROLLING MACHINES.

Specification forming part of Letters Patent No. 176,763, dated May 2,1876; application filed March 2, 1876.

To all "whom it may concern Be it known that I, JAMES C. WELLS, ofWarren, in the county of Warren and State of Pennsylvania, have inventeda new and Improved Bed for Leather-Rolling Machines; and I herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing, forming part ofthis specification.

This invention relates to that class of rolling-machines which use abed, on which the leather is placed, and then traversed by a vibratingor reciprocating roller on top of leather; and consists of certainimprovements therein, which will be particularly described hereinafter.

In cast-iron roller-beds heretofore used, the" a composition face andthe cheapness of a cast-iron bed.-

Figure 1 is a side view of the device. Fig. 2 is a top view of same.Fig. 3 is a crosssection through middle of bed.

The cast-iron bed B, as shown in Fig. 1, is made witha recess in itsupper side, of suitable depth to take in the plate or face F. The endsof this recess are out under on lines inclining toward the center fromwhich the curve is described, thus making a dovetail,

into which the face F is driven. .The ends of the recess'also cross thetop of bed at a slight angle to its sides, as shown in Fig. 2.

After the face is driven to its place it is still more securelyfasteliedby hammering or drawing it until it is perfectly secured to bed, thusdispensing with bolts or rivets, and at all times firmly holding theface in place.

Having described my invention, I claim as new and wish to secure byLetters Patent- An improved bed for leather-rolling machines, consistingof an iron base and a brass or other suitable metallic compositionsupporting-surface, secured to the base, substantially as shown anddescribed.

' JAMES C. WELLS.
